The object in the other person's hand, which resembled a game console, immediately caught Last Order's attention.

"Wow! That's the latest handheld game console! Misaka Misaka couldn't help but follow it with excited eyes!!"

"What?! Last Order! No, don't follow me! This is a limited edition that Misaka went through so much trouble to buy! What if you break it?!"

Click. The door was then closed by Last Order and the side story.

Now, only Hatsune Miku and Kikyo Yoshikawa are left in the living room.

"...I'm so sorry."

"what?"

Hatsune Miku blinked.

Suddenly, Kikyo Yoshikawa, standing before him, began to speak to him in this manner.

"That kid... Accelerator, he acted so indifferent on your birthday, really..."

"Haha... It's okay. I've always been very clear about Yifang's personality, so it's fine."

After all, he's such a cold person; expecting him to say "Happy Birthday" is like the sun rising in the west.

Hatsune Miku smiled dismissively, but then something else occurred to her.

"Speaking of which... does Ms. Yoshikawa know his birthday?"

"Birthday?"

"Hmm... Although he already knows other people's birthdays, I still... don't know Yifang's birthday."

If possible, Hatsune Miku would like to prepare in advance so that she can put on a grand party for Accelerator when the time comes.

but.

"It's a pity that even he himself doesn't know his birthday."

“…Huh?”

This time, it was Hatsune Miku's turn to be stunned.

"No, I don't know my own birthday...?!"

"...It should be said that he deliberately forgot."

At this point, Kikyo Yoshikawa's expression gradually changed.

It has become very complicated.

"When he was ten years old, he was sent to a place called Teliyan."

This is a past that Hatsune Miku never learned from Accelerator.

"...It's called a research institution, but in reality, it's a place where all sorts of dirty experiments are conducted."

"Human experimentation, including brain tissue analysis, and even dumping the bodies of useless young children there..."

"Dispose of... a... corpse...?"

"...Oh, sorry, just pretend you didn't hear those words."

Noticing the girl's terrified expression turn deathly pale in an instant, Kikyo Yoshikawa sighed.

"In short, that child's life was spent there... It's conceivable that someone like him wouldn't even have a basic concept of what a birthday is, right?"

"...Then, on that side, he..."

"Ah... he even forgot his own parents on his own initiative, and even his birthday. It was all a conscious act on his own."

Hatsune Miku sat there, stunned.

Kikyo Yoshikawa shook her head.

"...However, if we're talking about important days, there is one day that he has always marked."

"Huh…?"

That was the day that changed the course of his life.

That was a past that Hatsune Miku never knew, also sealed away in the history of Accelerator.

"On that day, the child's life changed. He suffered a severe brain injury and had to rely on electrodes to maintain his life."

"However, similarly, although he was shot in the head that day... he also experienced a true rebirth."

Although he couldn't know his birthday, that day was the day that completely changed Accelerator's fate.

The date of that day was stated directly by Kikyo Yoshikawa.

"...August 31st."

The girl was stunned once again.

It was the exact same day as her birthday.

On that day, the number one monster in Academy City embarked on a completely different path from the past.

A driver walked down the street.

He looked around, intentionally searching for something.

then.

"welcome!"

The waitress greeted him with a smile.

"Excuse me, are you looking to order custom jewelry?"

The surrounding area was decorated with all sorts of gemstones.

But Accelerator didn't go to look at those things.

He walked straight up to the other person and took something out of his pocket.

—It was a sparkling, deep blue crystal.

"Eh…?"

"I'm asking you, does your shop support customers to create their own decorations by hand?"

The female shop assistant looked surprised, but Accelerator stomped his foot impatiently.

The other party nodded quickly.

"Yes, yes, that's possible! But... no one has ever requested this kind of service before, and the process is quite complicated..."

"No, I just need you to demonstrate it to me once. Don't worry about the possibility that I'm here to challenge you. You just need to demonstrate it to me once."

That's right.

He has his own plans.

"cheers!!"

Inside the lounge were a group of idols from VOCALOID.

Everyone gathered around the table, and although it was just some simple desserts, it didn't stop them from celebrating.

"Happy birthday, Miku!!"

"Thank you everyone... After this, let's all come to my apartment and celebrate together!"

After learning all this, Aiho Yomikawa took the initiative to ask Hatsune Miku to bring the idols from VOCALOID to her house so that they could celebrate together.

The idols in front of them all nodded.

"Miku-nee! You have to have a great time!"

"That's right, your birthday is a very important day, and you should bring that energetic vibe from today's live performance into your real life!"

"As expected, Miku is all about being energetic and cheerful, whether on stage or at her birthday party."

"I'll play your favorite game with you then, so get ready!"

Kagamine Len, Kagamine Rin, Megurine Luca, Meiko, Gumi…

Various idols kept sending him words of blessing, and he happily returned their smiles.

Everything is so beautiful.

This is my birthday.

…yes.

Being alone is beautiful.

"...What's wrong, Miku?"

Kaito, standing to the side, looked at himself with some surprise.

Hatsune Miku then fell into a slight state of contemplation.

Yes... I'm the only one enjoying my birthday alone.

Before I knew it, a certain figure appeared before my eyes.

"...It's okay, Kaito."

"Hmm... You just have to have a happy birthday, don't overthink it, okay?"

"Ok."

The brief greetings ended just like that.

Hatsune Miku left the live performance, and around 8 PM, the VOCALOID members went to the apartment to hold a party together.

Hatsune Miku walked alone on the road like that.

Because of her mental abilities, no one around her was attracted, so the girl walked quietly alone on the street.

“…Huh?”

a moment.

Under the dark night sky, a figure appeared on the street ahead.

Someone dressed in gray and white striped clothing, with a black and white striped overcoat.

The first one is white.

"One party...?"

The two walked side by side down the street and looked at each other.

"...Is today your birthday?"

"Um...didn't we already talk about that this morning...?"

Could he have... completely forgotten his own birthday...?

Such a thought flashed through Hatsune Miku's mind, and she looked somewhat disappointed.

But Accelerator remained unmoved.

He simply walked slowly towards me.

"Huang Quanchuan asked me to pick you up and take you back. He said that if idols go out, they are likely to run into paparazzi, and I don't want to get into any unnecessary trouble."

"...Ah...Is that so?...Yes."

"Go back quickly, I'm too lazy to say anything more."

……

Oh, I see.

Hatsune Miku clasped her hands together slightly and nodded listlessly.

She continued walking slowly forward like that.

His entire demeanor plummeted to its lowest point.

"...I've had enough."
